The utility model provides a device of fetching earth for detecting rotary cultivator hack rate, including transmission case 1 and the case of fetching earth of setting from top to bottom, 1 internal rotation of transmission case is provided with two second roller bearings 15, be connected with two hawsers 5 between two second roller bearings 15, still around being equipped with belt 16 on one of them second roller bearing 15, belt 16 and the equal fixed connection of two hawsers 5, the fixed two driving motor 10 that are provided with in upper end of the case of fetching earth, output shaft 11 of two driving motor 10 all stretches into in the transmission case 1 and links firmly with two second roller bearings 15 are coaxial respectively, the lower extreme of the case of fetching earth opens, the inside of the lower extreme of the case of fetching earth is rotated and is provided with two first roller bearings 6, two hawsers 5 all walk around two first roller bearings 6 after stretching into the case of fetching earth.
In the embodiment, the rotary cultivator is connected with and driven by the tractor, the soil sampling device is connected with the tractor, and the soil sampling device is located behind the rotary cultivator in the traveling direction of the rotary cultivator, so that soil sampling can be carried out on the soil after rotary cultivation, and the control device of the driving motor 10 can be arranged in a cab of the tractor, which is well known by those skilled in the art and will not be described in detail herein.
In the rotary tillage process of the rotary cultivator, the two driving motors 10 are controlled to be started, and then the two driving motors 10 respectively drive the two second rollers 15 to rotate, in the rotating process of the second rollers 15, the mooring rope 5 is unwound from one second roller 15 which is not provided with the belt 16 and is wound on the second roller 15 which is provided with the belt 16, and in the moving process of the mooring rope 5, the belt 16 is driven to be wound, so that the lower end of the soil sampling box is opened. After the rotary tillage is finished, the soil taking device is pushed to move downwards, and the source of the pushing force can be a cylinder, a hydraulic cylinder or a ball screw mechanism and other linear output devices, which are not described any more. After the soil sampling box is downwards inserted into the soil, the soil is crushed into the soil sampling box, then the two driving motors 10 are controlled to rotate reversely, then the two driving motors 10 respectively drive the two second rollers 15 to rotate reversely, in the process of the reverse rotation of the second rollers 15, the mooring rope 5 moves reversely and drives the belt 16 to move synchronously, the belt 16 is inserted into the soil after bypassing one of the first rollers 6 along with the mooring rope 5 until the belt 16 bypasses the second first roller 6 and then seals the lower end of the soil sampling box, and the soil crushed inside the soil sampling box is caught by the belt 16. And finally, lifting the soil sampling box upwards to finish the soil sampling process.
The soil sampling device only needs to control the whole body to move up and down and the two driving motors 10 when soil is sampled, and is convenient and quick. In the soil taking process, the soil is taken in a direct insertion mode, so that damage to soil blocks is reduced, the obtained broken soil can be fixed by the box wall of the soil taking box, the original state of the broken soil is kept, and the deformation of the soil caused by extrusion of the taken broken soil is avoided. In the process of sealing, the movement of the belt 16 is driven by the traction of the cable 5, and the large shaking is avoided, so that the further fragmentation of soil particles caused by shaking is avoided, and the extracted broken soil can be further kept in an original state. By ensuring that the soil crushing form is kept unchanged, the generated error can be ensured to be very small in the subsequent soil crushing rate detection process, the result accuracy for detecting whether a rotary cultivator is excellent is improved, and the rotary cultivator is beneficial to being put into practical production and application.
In this embodiment, the cable 5 is formed as a steel rope, and may be replaced with a high-strength nylon rope or a hemp rope, depending on the size of the actual device, while ensuring the strength.
Further, the connection mode of transmission case 1 and soil sampling case does: the top of borrow case has linked firmly four limiting plates 2 perpendicularly, and four limiting plates 2 divide into on average two sets ofly, and every group limiting plate 2 sets up to two, two limiting plates 2 coplanarities of the same group, and two sets of limiting plates 2 are parallel to each other, and 1 card of transmission case is established between two sets of limiting plates 2.
